when built for opengl (as in QT_CONFIG(opengl)), qImageFromVideoFrame cannot be used from worker threads:
- qImageFromVideoFrame calls initializeRHI
- initializeRHI calls QRhiGles2InitParams::newFallbackSurface
- QRhiGles2InitParams::newFallbackSurface docs state that "This function must only be called on the gui/main thread"
when running with the wayland qpa plugin, a warning is emitted:
> Attempting to create QWindow-based QOffscreenSurface outside the gui thread. Expect failures
we should either document/assert or try to lift this requirement
